In Jones' weekly appearances on 105.3 The Fan in Dallas, Jones heaped praise on the former Texas Tech coach for his skill at coaching up quarterbacks.

"I don't know of anyone that's more qualified in doing what he does and has a better track record doing what Kliff does regarding QBs … or regarding offenses," Jones said.

Jerry Jones on Kliff Kingsbury: "I don't know of anyone that's more qualified in doing what he does and has better track record doing what Kliff does regarding QBs...or regarding offenses. ...I wouldn't, if we were interested or not, comment on just how interested or not we are."

While Kingsbury had his struggles as a head coach, his ability to coach QBs is clear in the numbers and several NFL teams reportedly are showing interest in hiring him.

Rams head coach Sean McVay, considered one of the NFL's bright young offensive minds, reached out to Kingsbury about becoming an offensive assistant or a consultant.

Jones would not go so far as to say the Cowboys are going after Kingsbury.

"I wouldn't, if we were interested or not, comment on just how interested or not we are," Jones said.

The Cowboys, despite being in first place in the NFC East, currently rank 27th in the NFL in passing offense, a number skewed a bit by Dallas' sixth-ranked rushing game. Still, Dak Prescott's quarterback rating (95.4) puts him 17th among league QBs.

Since he began coaching in 2008 at the University of Houston, Kingbury's offenses have finished no worse than 11th in the nation in passing yards. They have finished third or better six times and first on three occasions.
